Kale, or leaf cabbage, belongs to a group of cabbage cultivars (brassica oleracea) that are grown for their leaves or as ornamental plants.
Kale plants have green or purple leaves and the centers of the leaves do not form heads.
Many varieties of kale are grown for their bright white, red, pink, lavender, blue, or purple ornamental leaves.
Ornamental kale is edible like other varieties, but may not taste as good.
